OpenSSL Out-of-bounds read affects Kerberos ciphersuites



Go to Vulnerabilities List


General Info


TC: 12106
Description: OpenSSL is a very popular library supporting SSL and cryptographic functions working on many different platforms.

A remote attacker could perform a carefully crafted SSL/TLS handshake against a server configured to use Kerberos ciphersuites in such a way as to cause OpenSSL to crash. Most applications have no ability to use Kerberos ciphersuites and will therefore be unaffected.

Versions 0.9.7a, 0.9.7b, and 0.9.7c of OpenSSL are affected by this issue. Any application that makes use of OpenSSL's SSL/TLS library may be affected. Please contact your application vendor for details.
